Abstract: A fishing lure includes a body with first and second opposed sides, a first member rotatably carried by the body and having first and second end portions disposed adjacent the respective sides of the body, a fin carried by each of the terminal end portions of the first member, and a second member rotatably carried by the body. A mechanism interacts with the first member and the second member, whereby rotation of the second member urges corresponding rotation of the first member.

Abstract: An adjustable-depth crankbait fishing lure for use in catching fish at user-selectable depths. The crankbait fishing lure is made of a buoyant yet hard body having the shape and general appearance of a bait fish. Attached to the body are at least one fish hook and a means to attach the body to a fishing line. Pivotable lateral fins are located at each side of the body and are user adjustable for either water surface operation or operation at varying depths. A means is provided, substantially enclosed within the body, for allowing both the user to select the desired fin pitch corresponding to a specific water depth, and in some embodiments, for automatically returning the fins to the original pitch setting if the pitch setting is disturbed due to underwater snags or fish strikes. In addition, the fishing lure is designed so that the means for changing the fin pitch is protected against inadvertent changes due to fish strikes, snags, or other underwater menaces.
